' GEORGE CLEVELAND, or GREENFIELDQINDIANA,

GLAss rEEnmo APPARATUB'FOR Tanks, POTS, mp SIMILAR BEGEPTAOLES.

To all whom it may concern:

Be it known that I, GEORGE E. CLEVELAND, a citizen of the United States of America,

residing at Greenfield, in the county ofHancock and State of Indiana, have invented certain new and useful Improvements in Glass-Feeding Apparatus for Tanks, Pots,

and Similar Receptacles, of which the foltherein to the accompanying drawing.

This invention relates to a glass feeding apparatus for tanks, pots and similarreceptacles, wherein raw material is m elted and treated until it has reached the proper consistency, fluidity for molding'or' gathering The primary object of this invention is to provide 'a novel feeding device for ejecting a predetermined quantity of molten glass into a suitable mold.

-' provide an apparatus for automatically filling molds, wherein positive and reliable means are employed for feeding a quantity of molten material to a mold, cutting off the material and operating the movable parts of the apparatus for filling other molds,

To this end, I have'devised a novel feeding apparatus that can be used in connection with tanks of various types, the feeding mechanism being extremely simple, durable,

economical and positive in operation and adapted to'save considerable labor in the production of'glass ware, and vitreous articles. I

My glass feeding apparatus will be presently described and reference will now be had to the drawings forming a part of this specification, wherein,

Figure 1 is a vertical sectional view'of the apparatus, partly in elevation, Fig. 2 is a sectional view of the apparatus a similar view taken on the line IIIIII of Fig. 1, Fig. 4-isaside elevation of the apparatus,.Fig. 5-is a vertical sectional view of'the apparatus ina slightly modified form of construction, Fig. 6 is an enlarged cross sectional view of a metallic shell used in connection with the apparatus, Fig. 7 is a similar view of a cup adapted tofit in the shell, Fig. 8 is an enlarged cross sectional view of a cooling metallic collar forming Fig. 9 is a'plan of the part of theapparatus,

moldsupport comprises a table 'In the accompanying drawings, I have conventionally illustrated a glass tank, wherein raw material is melted. The tank -is provided with an extension 2 having a 'compartmentB formed therein adapted toreceive a quantity of the molten glass within Patented0ct.2O,19 08.

the tank 1. The side walls of the extension with openings 4, whereby burners (not shown) can be inserted in the molten material in a fluidv state and of a con-' 3 sistency advantageous to the production of glass ware and articles.

The bottom ,5 of the extension 2 is provided with" a metallic plate 6, having an 0 enin 7 formed therein for a metallic cy in- I drical shell 8 fitting in the-bottom 5 of the extension, said bottom being cut awayto accommodate said shell and provide an openl'ing 9 through which the molten metal is IA further object of this invention is toadapted topass. The shell 8 is flanged and I compartment 3 for maintaining a batch of secured to the plate 6 by screws 10. In this The cup has a concavity- 12, corresponding in diameter to the opening 9 of the extension bottom 5, so also an opening 13 registering with an opening 14 formed in a metallic cooling collar 15 detachably mounted in an opening 16 provided therefor in the shell 5. The

: shell is supported a cup 11 made of clay or .a similar non-fusible material.

metallic cooling collar 15 is formed with a I circular chamber 17 through which water passes to maintain the collar ina cool state and prevent its destruction which otherwise would be the case due to the action of the molten material passing through the open- 1- ing 14 of said collar. The collar provides a I shearing surface for knives 18 arranged be neath the plate 6, these knives serving two purposes, namely, to close the opening in dially disposing theknives upon .a sleeve :19,

to the plate '22, carried by the frame-work 23 of the tank 1. The sleeve 19 1s provided with a star wheel 2 1 for intermittently 14 and to shear the molten ma- 1 I terial after a certain quantity has passed Linto a mold. This isaccomphshed by ra 1001. said sleeve being revolubly mounted upon a standard 20, carried by a bracket 21, fixed regularly disposed pins 26 corresponding in number to the molds 27 carried by the table or support, said molds having a certain relative position to said pins as will be presently described. The table is fixed to a vertical shaft 28 carrying a beveled gear wheel 29.

Beneath the shaft 25 is a bearing 30 for a shaft 31 driven from a suitable source of power..' This shaft carries a gear wheel 32 and a movable beveled gear wheel 33 adapted to mesh with the beveled gear wheel 29 of the vertical shaft 28. The beveled gear wheel 33 is moved into and out of engagement with the beveled gear wheel 29 through the medium of a suitable clutch mechanism 34, illustrated conventionally in Figsland 3 of the drawings, said mechanism being manipulated by a lever 36. w

Arranged adjacent to the-table are bear ings 37 for a shaft 38, this shaft having a gear wheel 39 meshing with the gear wheel 32, and a grooved cam 40, the object of which will presently appear.

The extension 20f the tank has its roof or top 41 provided with an opening 42 directly above the opening 9 formed in the bottom 5 offthe extension. In the opening i 42 is movably mounted a plunger 43 of a diameter corresponding to that of the open- 1ng 9.- A plunger 43 is detachably carried by a rod 44 slida'bly mounted in a guide 45 fixed to the plate 22. The rod 44 is carried.

by a cross head 46 fixed upon the upper end of a' pitman 47, said pitman being slidably mounted and guided in a bracket 48. The lower end of the pitman 47 rests upon the grooved cam 40 of the shaft 38 and is reciprocated thereby. p

The operation of theapparatus as above described is as follows The shafts 31 and 38 continuously revolve and when the beveled gear wheel 33 is moved into engagement I with the beveled gear wheel 29, the table or mold support 25 is' rotated. This movement of the table, however, is intermittent, for as soon. as the mold is placed beneath the opening 14 of the collar 15, the operator moves the beveled gear wheel-33 out of engagement .with the beveled gear wheel,29, allowing the table to remain stationary, without interfering with the revoluble shaft 38. By ref- .erence to Figs. 2 and 3 of the drawings, it

I will be observed that the pins 26 are-located slightly in advance of the molds 27, whereby as the table 25 moves, the pin 26 will strike the star wheel 24 revolve sleeve 19 and move one of the knives 18 from beneath the collar 15. By the time this movement has been accomplished the mold is in position beneath the collar to receive the molten material from the compartment 3 of the extension 2.

The cam 40 of 'th'eshaft 38 now allows the pitman 47, rod 44, and plunger 43to descend 1 by gravity. As the plunger 43 enters the opening!) ofthe 'extenslon 2,, a quantity of molten. material within the cup 11 is severed from the remainder of the material in the extension. The material contained within the cup is forced through the opening 13 thereof and the opening 14 of the collar-into '7 the mold. Immediately upon the material being ejected into the mold, the plunger 43 recedes. The following operator now places the gear wheel 33 in engagement with the beveled gear wheel 29, and the table 25 is again moved. Since the pin 26 which first moved the star wheel 29, has not passed out of engagement with said star wheel, said wheel will be further moved to cause one of the knives to pass under the collar 15, sev- 30 ering the material and closing the opening 14. This movement of the knlves is accomplished before the plunger 43 entirely recedes from the cup 11, thereby preventing an inrush of molten material that might 35 pass through the collar were not a knife in position to close the same. The molds placed upon. the table 25 are successively filled, each mold being removed from the table after receiving the quantity of molten material and an empty'mold placed in position.

Reference will now be had to a slight modificat'on of my invention, illustrated in Fig. 5 of thedrawings. In this modification I employ air or steam under pressure for bore 51 of a rod 44, this rod being similar to the rod 44 withthe'exception of the bore 51. Connected to the rod 44*" is an air or steam supply pi e or holes 52 for admitting air or steam un. er pressure throughthe top 51, passageway 50 and concavity 49. The

cavityjend of the plunger 43 is always re-- tained in the molten material contained Within the extension 2, and its diameter is such as to rest upon the bottom of the extension, without entering the cup 11. Im- 11o mediately upon the plunger 43 being lowered tosever aquantity of molten material from that contained within the extension, the H pressure of air or, steam is turned on, and th1s air or steam v forces molten material from the cup 11' through the collar into the mold beneath the same. I attach considerable importance to the plunger irrespective of the mechanism em loyed for 'reciprocating the same. This p iinger can be used in the tank proper for forc ng a quantity of the contents thereof through an opening pro vided therefor in the bottom of the tank. The,c am'40 determines the stroke of the plu'nger'43, consequently the quantity. of

moltenmaterial forced into a mold can be governedby the stroke of the plunger, or by the size of the cup 11. For instance, in the manufacture of plate glass, thecup can be madesufliciently large for a batch of molten ciprocating' said plunger.

material, the quantity being sufiioient for the production of a large plate of glass. By providing a detachable shell, cup and collar, these parts of the apparatus can be readily renewed. I
